NOT KNOWN FACTS ABOUT BIREFRINGENT CRYSTAL

For optical fibers and also other waveguides, the excellence concerning uniaxial and biaxial does not apply, since the propagation way is actually based on the waveguide.The lessen section in the Michel-Levy chart (x-axis) marks the orders of retardation in multiples of roughly 550 nanometers. The area amongst zero and 550 nanometers is referred to
